Abstract: ABSTRACT OF THE DISCLOSURE         A process for fluidized catalytic cracking of heavy oils and production of hydrogen is described, comprising contacting steam and heavy oils with fluidized catalyst particles containing reduced iron at high temper-atures, wherein a fluidized bed is formed such that the catalyst particles are fed from the bottom and withdrawn from the top of the fluidized bed  and the fluidized bed is provided with a means for retarding the mixing rate of the catalyst particles in the vertical direction, to thereby generate a temperature difference between zones of the fluidized bed above and below said means, and use the upper zone for cracking of heavy oils and the lower zone for production of hydrogen.  Catalyst particles withdrawn from the fluidized bed may be regenerated and recycled.          Thus, light oils and hydrogen can be produced in high yields.

Abstract: IMPROVED COOLING SYSTEM WITH REDUCED WINDAGE LOSS               ABSTRACT OF THE DISCLOSURE          A sealed rotor motor has axially extending ventilation ducts in the poles.  A first stationary set of turning vanes is disposed adjacent one end of the rotor in flow communication with the ventilation ducts to provide an initial tangential velocity to coolant gas in the direction of rotor rotation.  A second stationary set of turning vanes is disposed adjacent the opposite end of the rotor in flow communication with the ventilation ducts to receive said cooling gas which has a velocity in the direction of rotation and direct it into a circulation system for cooling and return to the first set of turning vanes.  The two sets of vanes reduce the windage loss in the motor.

Abstract: CRYPTOGRAPHIC TRANSMISSION SYSTEM            Abstract In a cryptographic communication system, a first encryptor transmits to a first decryptor and a second encryptor, co-located with the first decryptor, transmits to a second decryptor, which is co-located with the first encryptor.  Each encryptor/decryptor pair is adapted to communicate using a selected non-self-synchronizing cryptographic mode.  Whenever it is determined that synchronization between, say, the first encryptor and the first decryptor has been lost, both the first decryptor and the co-located, second encryptor are switched from the non-self-synchronizing mode to the self-synchronizing mode.          This causes a loss of synchronization between the second encryptor and second decryptor since the latter is still operating in the non-self-synchronizing mode.  Upon detection of this loss of synchronization, the second decryptor and the co-located, first encryptor are also switched from the non-self-synchronizing mode to the self-synchronizing mode.  In due course, then, synchronization in both transmission directions automatically restores.        Return of each encryptor/decryptor pair to operation using the non-self-synchronizing mode is thereafter initiated by having each encryptor transmit a string of "1"s is followed by a "0".  The encryptor thereupon returns to the non-self-synchronizing mode.  The string of "1"s is long enough to ensure that synchronization with the encryptor is re-established and when the "1"-to-"0" transition is detected at the decryptor, it, too, is switched back to the non-self-synchronizing mode.

Abstract: Abstract A vented, nestable-extendable pouring spout for use with a container having an opening therein includes an annular mounting portion adapted to be secured to an annular lip encompassing the opening of the container.  A generally funnel shaped flexible body portion is secured at its larger circum-ferential edge to the mounting portion and at its smaller circumferential edge to a tubular neck portion located inwardly of the mounting portion.  The body portion has an invertible fold portion adjacent the mounting portion to which is attached a plurality of circumferentially spaced ears, each ear having a pair of cylindrically shaped nibs extending therefrom.  In the nested orientation of the spout, the ears extend downwardly out of the way of the nested neck and body portions.  As the spout is extended, causing the invertible fold portion to invert, each ear rotates inwardly about its point of attachment until the ears extend inwardly perpendicular to the longitudinal axis of the spout.  In this orientation, the ears and nibs define a central  flow aperture having a dentated perimeter for the outflow of liquid and a plurality of peripheral vent openings, one between each ear, for the inflow of air.

Abstract: ABSTRACT     A floor sweep auger system for mounting in an existing grain bin of the type having a wood or concrete floor and a cylindrical wall.  A stationary auger is mounted with an inner intake end secured to the floor at the centre of the bin and an outer discharge end extending through the wall of the bin at a location above the floor.  A moveable auger, which has a length substantially equal to the radius of the bin, is mounted for sweeping an arc of approximately 360°.  A centre mounting coupling of the moveable auger, which has a fixed pivot axis and a moveable pivot axis, allows the moveable auger to start from a position parallel to and adjacent one side of the stationary auger and to swing through the arc to a terminal position parallel to and adjacent the opposite side of the stationary auger.  The system is particularly designed for use in existing grain bins without requiring any modification to the floor and yet will allow a pick-up of substantially all of the grain in the bin without any manual movement of the grain.
